Bunch of assertion errors in dev environment
Closed this issue · 3 comments
Skript/Server Version
2.11.2I use config.sk setting script loader thread size: 1 so this could be the culprit.

Steps to Reproduce
load the dev environment gradlew skriptTestDev
This is because Variables#serialize() can only run on the main thread and is being called off it.
However, I'm not seeing these assertions fail when running skriptTestDev on a clean dev/feature with the script loader setting changed to 1.
